At least with too cold you can turn the heating up and put on loads of clothes when it's too hot you can't just open the window... All that happens is more hot air gushes in.

A nice mild 10-14 degrees, warm enough to wear a t-shirt but cool enough to not melt into a salty pool whenever you do anything.
If I had to choose from your options I'd say hot, just because cold generally means winter which means rain and short days, which are ****.
